Radio Frequency Interference Regulations
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio
communications.
Note : the 3262/63/67/68 Modem is a Class A product. In a domestic environment, this prod-
uct may cause radio interference, in which case the user may be required to take adequate
measures. Changes or modifications not expressly approved by Raymar-Telenetics could void the
user's authority to operate the equipment. This Class A digital apparatus meets all requirements of the
Canadian Interference-Causing Equipment Regulations.
This is a Class A product. Operation of this equipment in a residential environment may
cause radio interference, in which case the user may be required to take adequate measures to
correct the interference at his/her own expense.
This product is CISPR 22 Class B verified under test conditions that included use of shielded
DTE cables. Ferrite cylinders attached to the dial line are required for Modem 3266 (Can-
ada). Leased line cables with 1.5 turns through a ferrite cylinder were also used. Use of dif-
ferent cables will invalidate verification and increase the risk of causing interference to radio
and TV reception.
You can obtain the proper cables from Raymar-Telenetics.
Manual is current for Release 8.0 of the 326X Series Modem.

Overview
The 326X product documentation set includes the 326X V.34 Series Modem Reference Card.
Optionally, with a 326X Series Modem card backplane (to install a 326X card into a Modular Nest 9
or 21 enclosure), you receive the following:
•326X Series Modem Cards
Throughout this guide, references to the 326X Series Modem apply to 326X V.32bis, 326X V34, and
326X-SDC Series Modem, unless stated otherwise.
326X Series Modem Family
The 326X product family consists of three series: V.34, V.34 SDC, and V.32bis.
This Series… Supports This
Modulation… This Maximum DCE Rate …. And This Maximum DTE Rate…
326X FAST V.34 ITU V.34 33.6 kbps 128 kbps, asynchronous
326X FAST-SDC ITU V.34 33.6 kbps 128 kbps, asynchronous
and with proprietary
compression, 128 kbps
synchronous
326X ITU V.32bis 14.4 kbps 57.6 kbps,
asynchronous
IMPORTANT: When you select a modulation mode, you must ensure that the Max Rate (AT*MX)
and Min Rate (AT*MN) parameter options are within the valid range for the mode.
Some 326XFAST-SDC models are available with the V.35-compatible interface. This unit has a DB25
connector, so a converter is required.

CHAPTER ONE – About the Modem
Introduction
This chapter summarizes the features and options of the 326X Series Modem. The series includes:
-The 326X V.32bis Series Modem, which operates in V.32bis modulation mode
-The 326XFAST Series Modem, which can operate in V.34 modulation mode
-The 326XFAST-SDC Series Modem, which can operate in V.34 modulation mode and the
Synchronous Data Compression mode
In this guide, references to the modem apply to all of the above, unless stated otherwise.
IMPORTANT: When you select a modulation mode, you must ensure that the Max Rate (AT*MX) and Min
Rate (AT*MN) parameter options are within the valid range for the mode.
The modem provides reliable data communication over 2-wire dial lines and 2-wire or 4-wire leased lines,
depending on the model. Dial lines are public lines to which all telephone users have access; leased lines,
also called private lines, provide a dedicated connection, over lines provided by the telephone company.
Whether you use dial or leased lines, you can operate the modem as follows:
-Using the front panel: control keys and liquid-crystal display (LCD)
-Using industry-standard (AT and AT&), and Raymar-Telenetics-enhanced (AT*) AT
commands from an attached terminal, or commands from an asynchronous communications
software package running on an attached PC
-From a network management system (NMS)
-Using call establishment methods, such as V.25bis or LPDA2 automatic call units (ACUs)
Figure 1-1 shows desktop, or standalone, modems. The device is also available in high-density nest cards,
which offer the same features, and can be installed in Raymar-Telenetics’ Modular Nest 9-slot and Modular
Nest 21-slot rack-mounted enclosures.

SAFETY AND OPERATIONAL NOTICES
Repair
Warning
Do not attempt to repair the modem or enclosure. They contain no electronic components that can be
serviced or replaced by a user. Any attempt at user service of the 326X enclosure, or opening of the
326X unit, voids the product warranty.
Avertissement
N’essayez pas de réparer le modem ou le boîtier. Ils ne contiennent aucun composant électronique
pouvant êtreréparé ou remplacé par un usager. Toute tentative de réparation du boîtier du 326X par
un usager, ou toute intervention à l’intérieur du 326X, annule la garantie du produit.

Warnung
Versuchen Sie nicht, das Modem oder sein Gehäuse zu reparieren. Es sind keine durch den Benutzer
wartungs- oder austauschfähige Teile darin enthalten. Bei jeglichem Öffnen oder Wartungsversuch am
326X bzw.
Lightning
Warning
All Raymar-Telenetics devices should be used in environments designed for computers and electronic
equipment. In areas susceptible to lightning, take precautions to prevent damage to electronic
equipment. Contact your telephone company, or an electronic accessories vendor, for information on
lightning protection equipment. Customers experiencing problems caused by surges from lightning
have eliminated such problems by installing appropriate surge suppressors on power and data lines
connected to Raymar-Telenetics devices.
Avertissement
Tous les dispositifs Raymar-Telenetics doivent être utilisés dans des environnements conçus pour des
ordinateurs et du matériel électronique. Dans les zones susceptibles d’être frappées par la foudre,
prenez des précautions pour éviter que le matériel électronique soit endommagé. Contactez votre
compagnie téléphonique, ou un vendeur d’accessoires électroniques, pour obtenir des renseignements
concernant les systémes de protection contre la foudre. Certains usagers confrontés à des problèmes
causés par des sautes de tension dues à la foudre ont éliminé ces problèmes en installant des régulateurs
de tension appropriés sur les câbles électriques et les câbles de données reliés aux dispositifs Raymar-
Telenetics.
Warnung
Raymar-Telenetics – Geräte sind grundsätzlich in für Rechner und elektronische Anlagen
vorgesehenen Umgebungen zu verwenden. In unwettergefährdeten Bereichen ist jegliche Elektronik
gegen Blitzeinwirkung zu schützen. Näheres über entsprechende Schutzeinrichtungen erfahren Sie von
Ihrer Telefongesellschaft oder einem Elektrohändler. Problem emit Spannungsstößen durch
Blitzeinwirkung lassen sich durch Einbau von Überspannungsableitern in die zu Raymar-Telenetics-
Geräten führenden Netz- und Datenleitungen beheben.

OPERATING THE MODEM FROM THE FRONT PANEL
The front panel menus are organized functionally so that operation is easy for novice and advanced users.
Refer to Chapter 3, Getting Started, to learn about front panel operation.
SELECTING PROGRAMMED OPTION SETS
Option sets make it easy to use a modem with common applications, including:
•Asynchronous and synchronous answering
•Asynchronous and synchronous dialing
•Leased line with dial restoration operation
Four sets of options are stored in nonvolatile memory. If none is appropriate to an application, you can
customize an option set, and save it in nonvolatile memory.
Refer to Chapter 4, Configuring the Modem, for more information on option sets.
AUTOMATIC CALLING INTERFACES (ACUs)
The modem supports three automatic calling interfaces (also known as Auto-Call Units). ACUs let you execute
functions from a keyboard.
AT ACU
The asynchronous AT ACU is compatible with the industry-standard AT command set. AT Commands
provide a standard modem communications interface, allowing you to configure and operate your modem
from a terminal or PC keyboard.
Using the AT-compatible command set (AT and AT&), you can, for example, dial and receive phone calls.
Raymar-Telenetics’ extended AT command set (AT*) includes other important parameters used in
configuring advanced modem features.
Refer to Chapter 3, Getting Started, and Chapter 5, Using the AT Automatic Calling Interface, to learn more
about the AT ACU and AT command syntax.
V.25bis ACU
For sync or async auto-calling, use the ITU-T V.25bis compliant ACU.
With either the AT or V.25bis ACU, you can store, dial, or change up to nine phone numbers in the
modem’s electronic telephone book, directly from your terminal.
Refer to Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide, for details.
